Definitions

  • the present invention relates to tape tab fasteners that may be used with disposable absorbent articles comprising tape tab closure members.
  • Disposable absorbent articles such as diapers, training pants, incontinence garments, feminine hygiene garments and the like have become very popular in the market place today.
  • adhesive tape tabs fasteners are used to secure the absorbent articles about the waist of the wearer.
  • Such fasteners are generally manufactured separately from the absorbent articles to which they are attached.
  • tape tabs are manufactured by applying a release agent to a backing and winding the backing onto a roll.
  • the roll of backing material treated with a release agent is then unwound and coated with pressure-sensitive adhesive, forming a tape stock.
  • the tape stock is then rewound onto rolls for shipping.
  • the tape stock is unwound, cut to size, and joined to the chassis of an absorbent article.
  • An overriding consideration in the construction of a disposable absorbent article is the cost of manufacturing the absorbent article, and thus the cost of manufacturing the tape tabs to be used with the article.
  • the present invention provides a reduced cost tape tab fastener that has been found to work well with disposable absorbent articles.
  • a disposable absorbent article comprising: a topsheet; a backsheet joined with said topsheet; an absorbent core disposed between said topsheet and said backsheet; and a two-piece tape tab comprising: a backing substrate having a first surface, a second surface, a first edge and a second edge; a pressure-sensitive adhesive disposed on said first surface of said backing substrate; a construction adhesive disposed on said first surface of said backing substrate spaced inwardly from said second edge of said backing substrate a distance greater than or equal to about 0.5 mm, said construction adhesive joining said backing substrate with said backsheet; a release substrate having a release surface, an adhesive surface, a first end and a second end; and a permanent adhesive disposed between said adhesive surface of said release substrate and said topsheet, said permanent adhesive joining said release substrate to said topsheet.
  • the tape tabs of the present invention may be manufactured according to the following method.
  • the first step is to provide a backing substrate upon which the adhesives of the tape tab can be applied.
  • a pressure-sensitive adhesive is applied to regions of one side of the backing substrate.
  • the pressure-sensitive adhesive is applied in zones that are located transversely inwardly from the longitudinal edges of the backing substrate at least 0.5 mm. It is also preferred that the pressure-sensitive adhesive zones be separated about the longitudinal centerline forming an area free of adhesive at least 0.5 mm in width.
  • the pressure-sensitive adhesive preferably functions as the adhesive used to fasten an element of the absorbent article, such as a front waist region, to another element of the absorbent article, such as a rear waist region.
  • the backing substrate is then slit in a direction parallel to the machine direction and the release surface of a release substrate is placed in contact with the pressure-sensitive adhesive, forming a laminate comprising the backing substrate and the release substrate.
  • the release substrate preferably covers the entire surface of the backing substrate upon which pressure-sensitive adhesive has been applied. However, in a preferred embodiment, at least a portion of the backing substrate extends outwardly in a direction parallel to the cross machine direction beyond the longitudinal edges of the release substrate.
  • the surface of the laminate including the surface of the release substrate that is not in contact with the pressure-sensitive adhesive, and any of the backing substrate not covered by the release substrate is then coated with a construction adhesive.
  • the construction adhesive is applied such that there are areas free of construction adhesive of at least 0.5 mm in width along the longitudinal edges of the release substrate and about the longitudinal centerline of the laminate. (The construction adhesive is used to join the tape tabs to the absorbent article.)
  • the laminate is slit in a direction parallel to the machine direction and either rewound for shipping or storage, or fed to a taper unit that is integrated into the absorbent article manufacturing line. The taper unit cuts individual tape tabs and applies them to the absorbent article chassis.
  • the above-described method for manufacturing the tape tab fasteners of the present invention eliminates the need to apply a release agent to the surface of the backing substrate to which no adhesive is applied. Further, the method can be performed concurrently with the manufacture of the absorbent article to which the tape tabs are to be attached, thus, eliminating the need to rewind the tape stock. Therefore, a simplified and more economical process is provided for manufacturing tape tabs for use with disposable absorbent articles.
  • An alternative embodiment of the present invention provides a one-piece tape tab.
  • the method for manufacturing the one piece tape tab of the present invention is similar to the method described above.
  • a backing substrate is provided and a pressure-sensitive adhesive is applied to one surface of the backing substrate.
  • the backing substrate is then slit in a direction parallel to the machine direction.

  • the release tab 85 as shown in FIGS. 5 and 6 provides the user with a portion of the backing substrate 52 which is free of pressure-sensitive adhesive 54 and preferably not adhered to the release substrate or any other element of the diaper 20. Thus, the user may grasp the release tab 85 and more easily open the tape tab 40.
  • the term "open the tape tab” refers to separating the pressure sensitive adhesive 54 disposed on the tape tab 40 from the release substrate 50 or any other surface to which the pressure-sensitive adhesive 54 may be adhered.
  • alternative methods of providing a release tab 85 are available. The methods include, but are not limited to, folding a portion of the backing substrate 52 adjacent the inner longitudinal edges 83 onto the pressure-sensitive adhesive 54 disposed on the backing substrate 52 (shown in FIG. 5), or coating the backing substrate 52 adjacent the inner longitudinal edges 83 with a release agent or any other material that will prevent the pressure-sensitive adhesive 54 in the area adjacent the inner longitudinal edges 83 from adhering to the release substrate 50 or any other elements of the diaper 20.
  • the backing substrate 52 is preferably slit along the longitudinal centerline L, forming two backing substrate segments, 90 and 92. (Embodiments are contemplated, however, wherein more than two zones of pressure-sensitive adhesive 54 are applied to the backing substrate 52 and wherein the backing substrate 52 is slit and separated into more than two backing segments.)
  • the backing substrate segments, 90 and 92 are preferably separated transversely before they are brought into contact with the release substrate 50 (shown in FIG. 3d).
  • the release substrate 50 has a release surface 94 and an adhesive surface 96 opposed the release surface 94.
  • the release surface 94 is preferably comprises a release agent as described above, and is placed in contact with the pressure-sensitive adhesive 54 disposed on the first surface 80 of backing substrate segments 90 and 92.
  • the release substrate 50 at least partially covers both the first zone 86 and the second zone 88 of pressure-sensitive adhesive 54; the first zone 86 being disposed on segment 90 and the second zone 88 being disposed on the segment 92 of the separated backing substrate 52.
  • the laminate 60 has an outer surface 62, an adhesive surface 64, a longitudinal centerline L1 and a transverse centerline T1.
  • the adhesive surface 64 of the laminate 60 comprises the adhesive surface 96 of the release substrate 50.
  • the laminate 60 is preferably passed adjacent a spray nozzle 150 that applies a construction adhesive 56 to the adhesive surface of the release substrate 50.
  • the construction adhesive 56 may be applied to the entire adhesive surface 96 of the release substrate 50.
  • FIG. 3e has an outer surface 62, an adhesive surface 64, a longitudinal centerline L1 and a transverse centerline T1.
  • the adhesive surface 64 of the laminate 60 comprises the adhesive surface 96 of the release substrate 50.
  • the laminate 60 is preferably passed adjacent a spray nozzle 150 that applies a construction adhesive 56 to the adhesive surface of the release substrate 50.
  • the construction adhesive 56 may be applied to the entire adhesive surface 96 of the release substrate 50.
  • the construction adhesive 56 is applied laterally inwardly from the side edges 100 of the release substrate 50 up to about 0.5 mm to ensure the cleanliness of the process. (As noted above, the adhesive may be applied continuously or in any pattern.) In another preferred embodiment, the construction adhesive applied in transversely separated zones such that an adhesive free area 101 is present preferably parallel to and juxtaposed or coincident with the longitudinal centerline L1. The adhesive free area 101 is preferably greater than or equal to about 0.5 mm to aid in the slitting operation that takes place at shear slitter 160.
  • the construction adhesive 56 preferably comprises a permanent, hot melt adhesive as described above.
  • the laminate 60 is preferably slit along its longitudinal centerline L1 and separated to form tape tab stock 70, as shown in FIG. 3f.
  • the tape tab stock 70 has a longitudinal centerline L2, a transverse centerline T2 perpendicular to the longitudinal centerline L2, an adhesive surface 102 and a non-adhesive surface 104.
  • the tape tab stock 70 is preferably fed directly into the taper unit 170 that can be integrated into the absorbent article manufacturing line.
  • the taper unit 170 cuts the tape tab stock 70 in a direction parallel to the transverse centerline T2 to form the individual tape tabs 40.
  • the taper unit 170 then joins the adhesive surface 102 of the tape tabs 40 to individual absorbent articles manufactured concurrently with the tape tabs 40.
  • the tape tab 40 is joined to the chassis of the absorbent article with a permanent construction adhesive as described above with regard to the two-piece tape tab.
  • the steps described above relating to the preparation of a backing substrate 52 comprising zones 86 and 88 of pressure-sensitive adhesive 54 are followed.
  • the pressure-sensitive adhesive 54 is preferably applied in zones that are transversely separated about the longitudinal centerline L3 such that the width between the zones is greater than or equal to about 0.5 mm.
  • a construction adhesive 56 is applied to the second surface 82 of the backing substrate 52.
  • the construction adhesive 56 is applied continuously to the backing substrate 52 in zones, rather than to the entire second surface 82 of the backing substrate 52.
  • the zones of construction adhesive 56 are preferably transversely separated about the longitudinal centerline L3. Further, as shown in FIG. 6, the zones of construction adhesive 56 are preferably disposed transversely inwardly or transversely outwardly from the zones of pressure-sensitive adhesive 54 and preferably disposed inwardly from edge 84 greater than or equal to about 0.5 min. This ensures that at least a portion of the backing substrate 52 comprising the pressure-sensitive adhesive 54 can be folded over the first surface 80 of the backing substrate 52 to form a tape tab 40 once the backing substrate 52 is slit into segments.
  • the backing substrate 52 is preferably slit along the longitudinal centerline L3 and separated, forming at least two backing substrate segments as described above. These backing substrate segments are fed directly into a taper unit 170 which cuts the backing substrate segments into individual tape tabs 40.
  • Each individual tape tab has a fixed end 77 and a releasable end 78.
  • the releasable end 78 preferably comprises the pressure-sensitive adhesive 54 applied to the substrate backing 52. (In especially preferred embodiments, the releasable end comprises a release tab 85 as described above.)
  • the fixed end 77 preferably comprises the construction adhesive 56 disposed on the second surface 82 and a release surface 95.
  • the release surface 95 may comprise any release agent known in the art, including but not limited to, silicone, wax, or clay; or the release surface 95 may be formed by impregnating predetermined portions of the backing substrate 52 with a release agent, or by embossing or bonding the backing substrate 52 such that a release surface 95 is formed.
  • a backing substrate 52 may be chosen that comprises areas of differing molecular structures, such as laminates or coextruded films, wherein at least a portion of the first surface 80 of the backing substrate 52 acts as a release surface 95.
  • the tape tab stock 70 is fed into a standard taper unit as is commonly known in the art.
  • One such unit as supplied by Curt G. Joa, Inc. of Sheboygan Falls, Wis., feeds the tape tab stock 70 to an anvil roll where the tape tab stock 70 is cut into individual tape tabs 40.
  • the individual tape tabs 40 are then slipped (spaced) and the fixed end 77 of each tape tab 40 is joined to the chassis of the absorbent article by means of the construction adhesive 56 disposed on the second surface 82 of the backing substrate 52.
